Description

SKIN LESION PROTECTOR RELATED APPLICATIONS This application claims the benefit under 119e of U.S. Provisional Application No. 60/567,823 filed on May 5, 2004, the disclosure of which is incorporated herein by reference. FIELD OF THE INVENTION The invention relates to a protector that adheres to the skin and optionally protects the skin and/or skin lesions from harmful electromagnetic radiation. BACKGROUND OF THE INVENTION Electromagnetic radiation from the sun, herein sun or sunlight, for example in the ultraviolet region of the sun's spectrum, is known to cause harm to skin and/or skin lesions.
Pigmented lesions, for example moles, may undergo malignant transformation in response to harmful sunlight, resulting in a malignant melanoma, a highly virulent skin cancer than spreads rapidly to vital organs and is often fatal. Creams that protect the skin against harmful sunlight are known, but may not provide adequate protection for skin lesion for one or more of the following reasons: i) skin lesions often have a topography comprising fissures, kerinatized skin or elevated areas that resist coverage by protective creams; and ϋ) skin lesions often project above the surrounding skin divest protective creams as they rub against apparel, for example a robe worn while in transit to a location in the sun. Skin tapes that have an inadvertent property of blocking sunlight, are known but usually come in a single width and dispense in rectangular patches. When removed following a day in the sun, each patch of tape leaves a large, unsightly, rectangular area of skin that stands out against adjacent tanned areas, making them less desirable for lesion protection. SUMMARY OF THE INVENTION An aspect of some exemplary embodiments of the present invention relates to a skin protector comprising a sunlight filter layer that filters one or more wavelengths of sunlight and an adhesive layer adapted to adhere the filter layer to the skin, h an exemplary embodiment, the filter layer is adapted to reduce harmful wavelengths of sunlight, herein harmful sunlight, associated with malignant transformation of moles. Alternatively or additionally, the filter layer is adapted to reduce harmful sunlight to other sunlight-sensitive skin lesions, for example actinic keratoses and/or lesions comprising reduced and/or absent pigmentation, herein vitiligo. In an exemplary embodiment, the filter layer comprises a spongy material that substantially conforms to uneven skin topography associated with skin lesions and/or surrounding skin. Alternatively or additionally, the filter layer comprises a non-spongy, shape- conforming material that substantially conforms to the topography of the skin lesion and/or skin. Optionally, the adhesive layer is located around the periphery of the filter layer so the center of the filter layer remains unattached to the skin and/or skin lesion, thereby reducing irritation to the skin and/or lesion. Alternatively or additionally, the peripheral adhesive layer serves to offset the filter layer from the skin so that the filter layer contacts only a portion of the skin lesion. Alternatively or additionally, the filter layer is shaped so that it forms an offset from the skin, thereby only contacting a portion of the skin and/or skin lesion. In an exemplary embodiment, the center of the filter layer has a greater concentration of filtering material than that of the periphery so that the skin lesion is protected from harmful waves and the surrounding skin receives sunlight that causes tanning. In an exemplary embodiment, a kit is provided that includes the skin protector in two or more diameters, tanning protection and/or shapes. Alternatively or additionally, the kit includes a mirror that can be used to aid in positioning of the protector in hard-to-visualize areas. Optionally, the kit includes a map of places where a particular user needs to affix a skin protector.

BRIEF DESCRIPTION OF FIGURES The present invention will be more completely understood and appreciated from the following detailed description of exemplary embodiments of the invention, taken in conjunction with the drawings. Corresponding structures in different drawings are indicated with the same reference numeral. The drawings are: Figs. 1A-1B and Fig. 2 are schematic views of a skin protector attached to an area of skin, in accordance with an exemplary embodiment of the invention; and Figs. 3 and 4 are schematic views of a skin protector attached to an area of skin, in accordance with an alternative exemplary embodiment of the invention. DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS Figs. 1 A and 2 are side and aerial (transparent) schematic views, respectively, of a skin protector 100 attached to an area of skin 102 comprising a skin lesion 104, for example a mole. In an exemplary embodiment, protector 100 comprises an adhesive layer 110 that serves to adhere filter layer 120 to skin 102 and/or skin lesion 104. In an exemplary embodiment, filter layer 120 filters sunlight waves 130 and/or 170 that may cause lesion 104 to undergo malignant transformation when lesion 104 comprises a mole. Alternatively or additionally filter layer 120 applies to skin 102 and filters waves 130 and/or 170 that are harmful to skin 102 and/or other skin lesions 104, for example waves that cause malignant transformation of actinic keratoses and/or vitiligo (hereinafter referred to generally as "moles"). Sunlight waves 130 and or 170 that are harmful to skin 102 and/or lesion 104 may comprise Ultraviolet- A radiation and Ultraviolet-B radiation. In an exemplary embodiment, adhesive layer 110 comprises a ring around the periphery of protector 100 and, for example, offsets at least a portion of the center of filter layer 120 from skin 102 and/or skin lesion 104. By offsetting adhesive layer 110, irritation to skin 102 and/or lesion 104 is reduced. In some embodiments, adhesion to the lesion is allowed, for example for moles. In an alternative embodiment, protector 100 is not layered with both a filter layer and an adhesive layer at adhesive areas 110 and/or at a periphery of protector 100. For example, only adhesive layer 110 may underlay only a backing layer (not shown). For purpose of manufacture, it may be convenient to have the filter layer act as a backing as well. Optionally, the backing layer and/or a filter layer are transparent to one or more visual light waves, for example appearing transparent or translucent. During exposure to harmful waves 130 and/or 170, it is often desirable that skin 102 around the periphery of skin lesion 104 is exposed to at least limited amounts and or spectrum of sunlight waves 130 and/or 170 so that it pigments and visually blends with skin 102 further away from skin lesion 104. In an exemplary embodiment, the filter density and/or spectral filtration wavelength range in the center of filter layer 120 filters is increased to filter waves 130 and 170 while the filter density and/or filtration in the periphery of filter layer 120 is decreased to allow transmittal at least some waves 170. Optionally, periphery of filter layer 120 filters sunlight that is harmful to skin lesions 104, but not harmful to skin 102. In an exemplary embodiment, adhesive 110 and/or filter layer 120 contains one or more tanning preparations 160 known to enhance tanning with minimal or no exposure to sun. Preparation 160, for example, contains melanocyte-stimulating compounds that cause skin melanocytes to release melanin, thereby causing skin 102 to become pigmented. With release of preparation 160, the area below protector 100 tans and blends in with surrounding skin 102 that has tanned as a result of exposure to waves 130 and 170. Alternatively or additionally, a coloring preparation may be provided in skin protector 100. Alternatively or additionally, other preparations, such as antibiotics, disinfectants, healing enhancers or anti-inflammatory materials are provided. Optionally, tanning preparation 160 is incorporated into protector 100 with a release mechanism so that skin 102 and/or skin lesion 104 increase in pigmentation the longer skin' 102 is exposed to sun. In this fashion, skin 102 and/or lesion 104 beneath protector 100 substantially duplicate the pigmentation of surrounding skin 102 that increases in pigmentation with longer exposure to waves 130 and 170. For example, Hydroxyacetone can be used to emulate tanning action. Optionally, protector 100 is adapted to release preparation 160 gradually during the length of time it is applied to skin 102 and/or lesion 104. Alternatively or additionally, exposure to waves 130 and 170 triggers continued release of preparation 160 so that preparation 160 tans skin 102 and/or lesion 104 only during sun exposure. Alternatively or additionally, body heat and/or perspiration trigger continued release of preparation 160 and/or facilitates absorption of preparation 160 into skin 102 and/or lesion 104. In an exemplary embodiment of the invention, preparation 160 is contained in a gel matrix or is microencapsulated (or otherwise encapsulated) so that its enclosure degrades under conditions of heat, humidity and or UN radiation, at a known rate. Alternatively or additionally to tanning related preparations, other chemicals may be provided for example, herbal preparations, homeopathic medicines, chemicals which are known to affect moles, dye and/or paint. Fig. IB is a side view of an alternative skin protector 200 in which filter layer 220 is curved (or otherwise protector 200 is non-planar) to create an offset 270 from at least a portion of skin lesion 104 and/or skin 102, thereby reducing irritation to skin 102 and/or lesion 104. Optionally, an adhesive section 210 is flat. Optionally, the curve is provided at manufacture. Optionally, offset 270 is adhesive on its inside so that it can be attached to an underlying skin protrusion. It should be noted that while Fig. 1A also shows an offset of the skin protector, optionally, the protector is substantially flat with the surface of the skin. In an alternative embodiment, adhesive layer/sections 110 serve to offset the entire protector 100. Figs. 3 and 4 are side and aerial (semi-transparent) schematic views, respectively, of a skin protector 300, comprising a filter layer 320 and adhesive layer 310, in accordance with an alternative exemplary embodiment of the invention. Optionally, filter layer 320 and/or an adhesive layer 310 comprise one or more materials that substantially conform to the topography of skin 102 and sldn lesion 104. For example, adhesive layer 310 and/or filter layer 320 comprise a foam material that forms a substantially negative impression of skin 102 and sldn lesion 104 upon application to skin 102. Alternatively or additionally, protector 300 comprises one or more non-spongy resilient materials that substantially conform to the shape of skin 102 and/or skin lesion 104. hi one embodiment of the invention, separate adhesive sections and foam sections are provided. In another embodiment, an adhesive layer underlays a foam layer. In an alternative embodiment of the invention, putty, optionally colored putty, for example formed of a gummy material, is applied to moles. Optionally, a sunblocking material is mixed into the putty. Optionally, color is mixed into the putty or gum. In an exemplary embodiment, foam-type skin protector 300 contains one or more preparations 160 that are known to enhance tanning with minimal or no exposure to sun, so the area below protector 300 blends in with surrounding tanned skin 102. Optionally, skin protector 300 comprises a material that blocks harmful sunlight from reaching skin 102 and/or lesion 104. Alternatively, protector 300 is opaque to sunlight and blocks all sunlight rays 130 and 170 from reaching skin 102. In an exemplary embodiment, a kit (not shown) is provided that comprises protector 300 (and/or 100) in two or more diameters adapted to cover two or more sizes of skin lesion 104. For example, at least one of the at least two skin protectors may have a diameter of between 0.5 centimeters and 1.5 centimeters and at least one of the at least two skin protectors may have a diameter of between 1.5 centimeters and 2.5 centimeters. Optionally, the mole covering area is 1mm, 2mm, 3mm, 4mm, 6mm, 8mm or any smaller, intermediate or larger size (diameter). The protector may extend, for example, 1mm, 2mm, 3mm, 4mm or more past the active area. Optionally, an applicator stick (optionally transparent) is provided, which stick includes a strip of skin protectors, with at least one protector with adhesive exposed. Applying the stick to flesh causes the exposed protector to detach from the stick (optionally being held by a weak adhesive) and attach to the body. Optionally, a next protector is advanced to a contact location on the stick, for example, the protectors being mounted on a strip. In an exemplary embodiment of the invention, a kit comprises a coloring agent (e.g., ink or food coloring, optionally pre-mixed for certain shades) suitable for coloring the skin protectors, to a matching skin tone. Alternatively or additionally, a plurality of different kits may be available, for example, pre-colored to match various skin tones and/or tanning needs. Alternatively or additionally the kit comprises protector 300 in two or more shapes adapted to cover two or more shapes of skin lesion 104. For example, skin protector 300 in a round and/or oval shape and protector 300 comprising two adjoining circular areas thereby forming a butterfly-like shape. Other shapes may be provided as well, for example, strip shaped or a shape with ragged edges. Optionally, protector 300 is provided with one or more of the following properties: (a) Elasticity, e.g., being made from elastic material.
